      CPU and System Topology

      Server Description

      Dedicated multi-core AMD EPYC compute instance featuring 48 vCPUs, 188 GB RAM, and bundled NVMe SSD storage for parallel processing.

      General PurposeStorage & Database

      Hetzner Cloud ccx63 is a dedicated CPU server provisioned with 48 vCPUs from 24 physical AMD EPYC cores operating at 2.0 GHz, coupled with 188.0 GB of RAM and 960 GB of local NVMe SSD storage. Operating on x86_64 architecture under the QEMU hypervisor, it features 32 MB L3 cache alongside AES, SHA_NI, and AVX instruction sets. Synthetic benchmarks demonstrate strong multi-core processing power, achieving top-tier performance in multi-threaded stress-ng, PassMark CPU execution, and software compilation tasks. Database throughput is notable, reaching over 62 million Redis SET operations per second. While single-threaded speed and memory bandwidth fall within average ranges, the dedicated vCPU model and high core count ensure consistent throughput. The instance is suited for multi-threaded compilation, database operations, backend web application clusters, and small-model LLM text generation.

      Workload Profiles

      2Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
